[node:test] Incorrect `SuiteContext` description

https://nodejs.org/docs/latest-v18.x/api/test.html#describename-options-fn

Description of the problem

Docs said that tha callback function in describe:

declaring all subtests and subsuites. The first argument to this function is a SuiteContext object.

But in fact SuiteContext is not the first argument. SuiteContext is this context:

import { describe } from 'node:test'

describe(function(foo) {
    console.log('First argument: ', foo)
    console.log('this: ', this)
})

> First argument:  []
> this:  { signal: AbortSignal { aborted: false }, name: '<anonymous>' }

[Semigradsky]

But TestContext is the first argument:

import { test } from 'node:test'

test(function(foo) {
    console.log('First argument: ', foo)
    console.log('this: ', this)
})

> First argument:  TestContext {}
> this:  TestContext {}

@MoLow it looks like the SuiteContext language was added in 389b7e1. It doesn't look like SuiteContext exists in the code though. Should all references to SuiteContext be replaced with TestContext?

[MoLow]

@cjihrig it is simply generated as an object literal

node/lib/internal/test_runner/test.js

Lines 739 to 741 in f8ce911

	getRunArgs() {
	return { ctx: { signal: this.signal, name: this.name }, args: [] };
	}

I think we should either change the docs to remove the use of SuiteContext since it doesn't really exist as a class or update the code to make it an actual class. I think updating the code would be easiest in this case.
